Problems solved by technology

[0003] (1) During the vibration grinding process, the charging interface shell 1 is rubbed against the resin abrasive, and the burrs on the edge of the charging interface shell 1 are removed through friction, but the color of the charging interface shell 1 will change after grinding, which is dull and dull. uneven;
[0004] (2) In addition, if Figure 4 As shown, the edges and corners of the resin abrasive protrude into the inlet of the charging interface shell 1 and contact the high-gloss surface 11, thereby producing scratches on the high-gloss surface

Example Embodiment

[0064] Example 1

[0065] Add 6kg of spherical chrome corundum with a specification of Φ7mm and charging interface shell 1 formed by 2400 CNC equipment into the grinding barrel of the rolling grinder, and rotate at a constant speed of 1400 rpm for 3 minutes. After the ground charging interface case 1 is cleaned, dried and sand-blasted, the above-mentioned charging interface case 1 and 6 kg of spherical zirconia grinding stones with a specification of Φ0.8 mm are added to the grinding barrel of the rolling mill together to Rotate at 1700 rpm for 5 min. After grinding, the obtained charging interface case 1 is cleaned and dried, and finally a finished charging interface case 1 with a high-gloss and high-gloss surface 11 is obtained.

Example Embodiment

[0066] Example 2

[0067] Add 6kg of spherical chrome corundum with a specification of Φ8mm and the charging interface shell 1 formed by 3000 CNC numerical control equipment into the grinding barrel of the rolling grinder, and rotate at a speed of 1500 rpm for 4 minutes. After the ground charging interface case 1 has been cleaned, dried and sand-blasted, the above-mentioned charging interface case 1 and 6 kg of spherical zirconia grinding stones with a specification of Φ1 mm are added to the grinding barrel of the rolling mill, and the grinding process is performed at 1800 rpm. Rotate evenly for 8 minutes at a speed of 1 / min. After grinding, the obtained charging interface case 1 is cleaned and dried, and finally a finished charging interface case 1 with a high-gloss and high-gloss surface 11 is obtained.

Example Embodiment

[0068] Example 3

[0069] Add 6 kg of spherical chrome corundum with a specification of Φ9 mm and charging interface shell 1 formed by 3600 CNC numerical control equipment into the grinding bucket of the rolling grinder, and rotate it at a speed of 1600 rpm for 5 minutes. After the ground charging interface shell 1 is cleaned, dried and sandblasted, the charging interface shell 1 and 6 kg of spherical zirconia grinding stones with a specification of Φ1.2 mm are added to the grinding bucket of the rolling grinder to Rotate evenly for 10 minutes at a speed of 1900 rpm. After grinding, the obtained charging interface case 1 is cleaned and dried, and finally a finished charging interface case 1 with a high-gloss and high-gloss surface 11 is obtained.

Abstract

The invention discloses a 3C product charging connector shell highlight process. The 3C product charging connector shell highlight process comprises following steps that firstly, a CNC numerical control device is adopted to machine a charging connector shell; secondly, grinding stone I and the charging connector shell obtained in the first step are added into a grinding bucket of a rolling grinding machine according to the proportion to be subject to rolling grinding, and the ground charging connector shell is cleaned and dried; thirdly, the charging connector shell obtained in the second stepis subject to sand blasting treatment; fourthly, grinding stone II and the charging connector shell obtained in the third step are added into the grinding bucket of the rolling grinding machine according to the proportion to be ground. The 3C product charging connector shell highlight process has the good highlight effect, the product yield and the stability can be improved, the machining flow time can be shortened, manpower is saved, material losses are reduced, product production cost is reduced, and the product market competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of processing parts of 3C products, in particular to a high-gloss process for charging interface shells of 3C products. Background technique [0002] like figure 1 As shown, the charging interface of 3C products such as mobile phones and tablet computers is provided with a charging interface shell 1, and the inner side of the entrance of the charging interface shell 1 has a high-gloss surface 11, which is the key processing part of the high-gloss process. Usually, the width of the inlet of the charging interface case 1 is not more than 2 mm. Figure 5 The processing flow of the charging interface case 1 in the prior art is schematically given. In the prior art, the charging interface shell 1 with preset shape and size processed by CNC numerical control equipment is ground in a vibration grinder to remove residual burrs after CNC processing, and after cleaning and drying, sandblasting, cleaning and drying ...
